This is a division order and by signing it you are not changing any of the terms in the base lease. Your .317 may be net acres but isn't diluted by the gross acres or royalty burdens or outstanding NPRI. This decimal is what you get paid on. So on $1,000,000.00 worth of oil sold you get $12.05.
The following is a sponsored (paid) promotional notice:
